COMPLEX REACTION TIME EXPERIMENTS WERE DONE WITH INFORMATION SIGNALS INDICATING WHICH REACTION WOULD BE REQUIRED IN CHOICE EXPERIMENTS. REACTION TIMES DECREASED WITH INCREASING INTERVAL BETWEEN INFORMATION AND STARTING SIGNALS, BUT WERE NEVER SHORTER THAN REACTION TIMES IN SIMPLE REACTION TIME EXPERIMENTS. LONGER EXPOSURE OF THE INFORMATION SIGNAL GAVE LONGER REACTION TIME. IN OTHER EXPERIMENTS IN WHICH INTERRUPTION SIGNALS WERE GIVEN SIMULTANEOUSLY WITH THE START SIGNALS, REACTION TIMES WERE SHORTER WHEN REACTIONS OCCURRED IN SPITE OF THE INTERRUPTION SIGNAL. WITHOUT THE SIGNAL, TIMES WERE LONGER BECAUSE SUBJECTS WAITED FOR THE INTERRUPTION SIGNAL.
